Low genetic diversity and shallow population structure in the broom hare, Lepus...
Costa, J; Queirós, J; Ballesteros, F; Mucci, N; Souto, J; Silva, E; Melo Ferreira, J; Alves, PC; Jose Melo-FerreiraThe broom hare (Lepus castroviejoi) is a threatened Iberian endemic, for which there is limited knowledge. We use genetic non-invasive sampling (gNIS; N = 185 faeces samples) and specimens from hunting and roadkills (N = 22) in conjunction with a 15-microsatellite panel and a 541-bp fragment of cytochrome-b to assess the genetic diversity, population structure and evolutionary history of this species. Populatio...

Detection and Molecular Characterization of Giardia and Cryptosporidium spp. Ci...
Lux, L; Ulrich, RG; Santos-Silva, S; Queirós, J; Imholt, C; Klotz, C; Paupério, J; Pita, R; Vale-Gonçalves, H; Alves, PC; Mesquita, JRSimple Summary Wild small mammals can be a veterinary and public health concern, because they can act as reservoir hosts for numerous pathogens and potentially transmit them to humans, domestic animals and other wildlife species. This study represents the first investigation of the diarrhea-causing parasites Cryptosporidium spp. and Giardia spp. in wild rodents and shrews from Portugal. Cryptosporidium spp. was...
Adaptive introgression underlies polymorphic seasonal camouflage in snowshoe hares
Alves, PC; Melo-Ferreira, J; Jones, MR; Mills, LS; Callahan, CM; Alves, JM; Lafferty, D; Jiggins, FM; Jensen, JD; Good, JMSnowshoe hares (Lepus americanus) maintain seasonal camouflage by molting to a white winter coat, but some hares remain brown during the winter in regions with low snow cover. We show that cis-regulatory variation controlling seasonal expression of the Agouti gene underlies this adaptive winter camouflage polymorphism. Genetic variation at Agouti clustered by winter coat color across multiple hare and jackrabbi...
